低压电力线载波通信路由算法研究

摘要

The topology of low-voltage distribution network is complex and unknown, and the power line communica-tion ( PLC) channel has interference and its status varies dynamically.And it causes the unreliable communication and affects the range of communication.The necessity of automatic routing is explored through the analysis of the low voltage distribution network topology in this paper.On the basis of traditional ant colony algorithm, a hybrid routing combined ant colony algorithm, genetic algorithm and particle swarm algorithm is proposed.Simulation results show that this method can improve the convergence speed and guarantee the global optimal.%低压配电网拓扑结构复杂未知，电力线载波通信信道干扰与时变造成通信不可靠，影响通信范围。本文对低压配电网拓扑结构进行分析，探讨了自动路由的必要性。在传统的蚁群算法基础上，提出了基于蚁群算法、遗传算法和粒子群算法相结合的混合路由算法。仿真研究表明，该方法能提高收敛速度和保证全局最优。
